ADHESIFE SUBSTANCE AND METHOD OF PREPARING THE SAME.

Application filed Kovember 28, 1908. Serial No. 464,919.

'To allwlwm 'it may concern:-

The joining of plain surfaced materials to glossy surfaces or the joining together of two glossy surfaces by the use of the usual adhesive. mediums, such as glue, gums, dextrius, paste and the like, whether the gloss has been obtained by polish, coating or otherwise and whether necessarily incident to the process of manufacture for commercial use or inherent in the substance itself, or is the result of some other substance coated upon the same, has always been difficult on account of the fact that such glossy surfaces afford insufficient hold for the adhesive medium. This renders adhesion by such means imperfect at best, even when such adhesive mediums are in a moist state and results often inthe complete separation of such surfaces when the moisture has dried out of the adhesive medium. Among these glossy surfaces to which this difficulty of adhesion a plied may be mentioned glazed, parafine or waxed paper or the like and varnish or japanned or similarly coated surfaces.

To accomplish the perfect and permanent adhesion of such surfaces without. the use of chemicals which may injuriously affect the materials to be joined, whether metals, cloths, papers, leathers, glass or othersubstances, and by the use of the ordinary adhesive mediums is the object of my invention. I accolnplish'this result by distributing or envelopirdg in the adhesive medium finely divided solid particles of matter capable of "piercing the surface to which the adhesive medium is to be applied in use.'

It is apparent that the adhesive medium maybe employed in any case where two sub-' stances are to be united. For example, the adhesive medium containing the finely divided particles of matter may be painted upon or otherwise applied to one or both the surfaces that are to be united with a brush or the like and the surfaces then brought together while the adhesive medium is still in a partially liquid condition, or if desired I may coat a strip, sheet or label of paper, cloth or other suitable material with the adhesive medium containing the finely divided particles 'of solid matter and permit the coating vto dry, thereafter moistening it for use. I have in practice prepared strip rolls having one or both surfaces coated with anzadhesive medium containing coated particles of matter.

In order that the principles of my invention may be readily understood, I have represented one manner of utilizing or carrying. out the invention in the accompanying. drawing, ivhereiu- Figure 1 represents a strip of material coated with an adhesive medium prepared inaccordance with my invention; Fig. 2 is a section of the strip shown in Fig. l, but upon an enlarged scale; Fig. 3 represents in cross section and somewhat diagrammatically the manner in which the strip shown in Fig. l is applied to materialv having a coated surface; and Fig. 4 is a similar.representation of the manner of applying an adhesive strip or the like to a non-coated surface.

In preparing the adhesive medium, I preferably employ glue, but any suitable medium may be used, such as 'dextrin, gum, paste or cement; In any suitable manner, I distribute through the adhesive medium finely divided particles of solid matter, as for example sand preferably having sharp edges or angles, emery, carborundum, finely comminuted glass or the like. Fine particles of sand have been effectively used for the purpose and this substance is desirable bevv cause of its cheapness. The 'adhesive medium having enveloped therein the particles of matter, may be applied, as by a brush, to one or both surfaces that-are to be joined together and the surfaces superposed one upon the other while the adhesive medium remains partiallv liquid, or the adhesive medium having enveloped therein sand or the like may be applied to a strip, sheet or label upon one or both faces dependent upon the use and permitted to dry thereon.

In Figs. 1 and 2, I have represented at 1 a portion of a strip having applied thereto an adhesive medium 2 in which are enveloped Specification of Letters latent. Patented Sept. 6, 1910.

suitable particles 3, the number of which in use depends upon the nature of the surfaces to be acted upon. As shown more clearly in Fig. 2, each of the particles 15 wholly coated with the adhesive ,medium so-as preferably to haveno exposed or;. ba-re portions. I Many receptacles, such for example as 7 paper boxes, arecomposed of a base :portion of card board or the like to which 1s applied an exceedingly thin glazed paper. A strip or sheet coated with'glue or other adhesive medium in the ordinary nianner can not be made permanently to adhere to many ofsuch glazed surfaces. The same-is true; of var- .nished, japanned and certain "other coated;

, surfaces. If, however, the strip coatedwith q the; adl1esive{,1nediunr having; enveloped ,t'herein' sand or other suitable particles be applied to the glazedsurfa'ce', thesandor other particles, impress themselves mto and.

In F ig- 4, I haverepresented 6 which may be metal .or someother-.mate-fl 'z rial to which an adhesive medium does not" readily adhere.- The, surface of the material 6 is roughened or penetratedtby the coated particles of sand or the like, the adhesive medium being applied in such inti-fv mate relation thereto as to cause the strip to adhere firmly thereto, j

In preparing the strip or sheet or in using" the adhesive medium, it is not necessary that all of the sand 01' other solid particleslbe coated with the said medium, and 'itgmay'in Y beyond.

- From the foregoing description, it: will be apparent that an adhesn'c medium prepared -or treatedin accordance with my invention may beeffe'ctively employed to join together :tw'o glossy surfaces, which otherwise could vnot be joined together permanently or only with extreme difficulty, and thatit may be employedto join a-plain surfaced material to a glossy surface, Whether as a sheet, strip or labellor in any'other desired manner.
